Hello there..
i have a weird problem from with the GPS (Location Service)
iOS i already tried : 3.1.2 , 3.1.3 , 4.0.1 , 4.1
Baseband : 05.13.04
WIFI / Unlock working..
when i am using the Google Maps built in App with the phone GPS working.
but when i use Third party Location Applications i cant get GPS Signal in none of them
i tried Push Fix and no luck at alll..
in iOS > 4 the GPS working for few seconds then signal lost

1.is Google maps Application working means GPS Hardware works correctly??
2.is there a possible fix for GPS for Third party Applications?

Thank you for ur Help..

Have you tried SAM? Subscriber Artificial Module

Also, have you tried setting up the phone as new?

i have the offical AT&T Sim and i can Activate it over iTunes is it matters
and yes i tried set the phone as New each time i restored..
